JOHN O. DAVISON, OF MEMPHIS, TENNESSEE.

ii CONCRETE BUILDING CONSTRUCTION.

To all whom it may concern:

Be it known that I, JOHN' O. DAVISON, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented new and useful Improvements in Concrete Building Construction, of which the following is a specification. V

The invention relates to building construction, and more particularly to the class of concrete building construction, which is an improvement over the subjectmatter of an application filed by me on or about the 10th day of January 1914:, and bearing Serial No. 811,457. a r

The primary object of the invention is the provision of a concrete building construcfasteners, and the requirement of skilled labor.

A further object of the invention is the provision of a structure of this character wherein the completed building is rendered damp-proof, practically fire-proof, and airtight.

Other objects will be in part obvious and in parthereinafter pointed out.

The invention accordingly consists in the construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claim.

' In the-drawings :Figure 1 is a fragmentary front'elevation of a building constructed in accordance with the invention, showing the window casement therein. Fig. 2 is :a sectional view on the line 2+2 of Fig. 1.

Fig. 3 is a sectional view on the line 33 of Fig. 1. Fig. 4 is a perspective view of a column for usein the house or in constructing a porch. Fig. 5 is a transverse sectional view therethrough. Fig. 6 is a perspective- Specificationof Letters Patent.

View of the sill of the window casement.

F the porch column, the same, together with v the slabs hereinbefore mentioned, will be hereinafter fully described.

The slabs A and B are each formed with substantially L-shaped outer locking flanges 11 and an intermediate substantially T- shape'd locking flange 12, while arranged between the outer and inner slabs A and B is a substantially H-shaped securing or looking member 13', each being adapted to interlock with thesaid flanges 11 and 12 of superimposed inner and outer slabs A and B for joining the same in producing the vertical wall 10.

The outer and inner corner slabs C and D r are formed with substantially L-shaped locking flanges 1 1, and substantially T- shaped locking grooves 15, with which are adapted to engage the locking members 13, one vertical series of the said members 13 adjacent to the corner slabs C and D each being formed with a substantially T-shaped locking extension 16 which is adapted to interlock with the vertical series adjacent thereto'of the members 13. In erecting the vertical wall 10 the outer and inner slabs A and B are arranged in rows parallel with each other, and the members 13 are positioned therebetween so that the flanges l1 and 12 will lock with the same, thus oining the said slabs to form a unitary structure. In the building of the wall 10 the next row of slabs A and B are arranged in staggered relation to the previously laid slabs and are joined together by the members 13, as before set forth. At the corner of the right angular walls the corner slabs C and D are united together as shown in the drawings, and the members 13 arranged at the corner in vertical series are joined to the extensions 16 of section 19, the sill sections being cut away at .to accommodate the lower ends of the stile section's18 which are supported thereon. All of the sections ofthe window casement E are formed with inner facing extenhead section 19 are formed with outer facing extensions 22, these extensions being disposed outside of the plane of the outer-and inner slabs A and B respectively. The head section'1 9is formed with slots 23 in which are journaled pulleys 24 over which are trained the sash cords, which together with the sashes are not shown. [The inner surfaces of the stile sections 18 and the head' section 19 are formed with grooves 25 in whichare inserted the parting strips 26 of the ordinary well-known construction for the guiding of the window sashes in the opening and closing thereof.

The slabs A, B, C and D, the'window casement-E, and the porch column F, to-

faces with substantially T-shaped locking members 27 which are adapted tointerlock with the flanges 14: of adjacent inner and outer slabs A and B'for the fastening of the building. V

In Figsdand 5 thereis shown a porch column which comprises the face slabs 28 formed with looking flanges 29 which, en-

Window casing within the wall 10 of the;

gage the locking ribs 80 of a substantially X- 7 shapedicore 31 which fits centrally within the column fornniting' the face slabs. column is built up in an identical manner as the Wall 10 of the building, and is used inthe: constructing of a porch therefor.

From i the foregoing it is thought that the construction of my device will be clearly understood, andthereforea more extended explanation has-been omitted.

What is claimed'is In a building construction, a sectional wall,- a casement comprising a base sill having 'euti-awaypportions inopposite ends thereof, .vertical stiles engaged in the notches, ahead piece supported by -thestiles, locking flanges formed on the stiles, flanges formed on the sections of thewall for looking engagement with the first-named flanges, the said-Vertical stiles and head piece being In testimony whereof I aflix my signature in-presencejofjtwo' witnesses.
